CA1 pyramidal neuron synaptic integration (Jarsky et al. 2005)

"The perforant-path projection to the hippocampus forms synapses in the apical tuft of CA1 pyramidal neurons.
We used computer modeling to examine the function of these distal synaptic inputs, which led to three predictions that we confirmed in experiments using rat hippocampal slices.

This 'gating' of dendritic spike propagation may be an important activation mode of CA1 pyramidal neurons, and its modulation by neurotransmitters or long-term, activity-dependent plasticity may be an important feature of dendritic integration during mnemonic processing in the hippocampus."
